In addition, the use of interface provides the advantage that can obtain more substantial data.Especially, data can be stored as extensible markup language (xml) data.

This structure presented especially makes it possible to manufacture flat electric interfaces module IM, thus minimize spatial demand makes it possible to obtain New function simultaneously.Especially, the structure presented makes it possible to provide have and is less than 36mm(and is particularly less than 23mm, is particularly less than 18mm, is particularly less than 13mm and is especially preferably less than 7mm) the electric interfaces module IM of width.

Such as, be in the embodiment of 7mm at width, this structure can make support 2(such as printed circuit board (PCB)) be equipped with SMD at least one side and there is NFCIO interface and actual interface element.Thus this support 2 can easily be disposed in narrow housing.In addition, support identifies zones of different 3a, 3b, 3c of the different task that such as can be used for electric interfaces module or the parts needed for this module.Alternately or additionally, zones of different 3a, 3b and 3c also can specify the different electromotive force groups of electric current isolation each other, and such as can connect by coupling element.Show this exemplary configuration in figs. 2 and 3.

Alternately or additionally, wired bus systems can also be provided.Especially, can also provide following exemplary bus system, it is arranged in attachment rail 11 and is contacted by independent electric interfaces module IM when being placed on attachment rail 11.

In another embodiment, regulation support 2 has the flat plane antenna 7 for integrated NFCIO interface.This makes the exchange of the improvement achieved between independent electrical interface module IM on the one hand and flat electrical interface module IM on the other hand.

Such as, integrated NFC interface can be built with being schematically shown as Fig. 2 and Fig. 3.Except being present in the transmitting and receiving unit of the reality in chip 6, NFCIO interface such as can also have flat plane antenna 7.In certain embodiments, chip 6 easily can also be built-in with antenna 7, or can add antenna as parts, such as, as coil.Obviously, this coil serving as antenna 7 can also be embodied as the enable parts of SMD or the antenna be embodied as in plastic casing or be bonded to housing wall by means of film.In addition, flat plane antenna also may be embodied as individual components.But in other side, flat plane antenna 7 also can by the conductor path manufacture on support 2.In addition, also by the connection of the suitable connection establishment on electric interfaces module IM and other parts.In order to example, show the connection via another interface 5 to controller 4 in figs. 2 and 3.Except unibus, example interface such as also can have other serial or parallel interface or such as other interface of bus.Controller can be microcontroller or other logical circuit any.

Fig. 2, Fig. 3 and Fig. 4 show the various views of different embodiment.Electric interfaces module IM is suitable for being arranged on attachment rail 11.An example of attachment rail 11 is lid track (caprail).

In the embodiment shown in Figure 2, (plane) antenna 7 is disposed near the installing zone of attachment rail 11.This reserves more installing spaces for actual interface parts, web member and display in the region of opposite side.

In the embodiment shown in fig. 3, (plane) antenna 7 is disposed in the region relative with the installing zone of attachment rail 11.This is convenient to the communication with external read device RW, thus can communicate (that is, exchanging data) with the electric interfaces module IM of larger distance.

For a person skilled in the art, be apparent that, other position can also be provided between (plane) antenna 7 and these two positions of chip 6, thus obtain at least part of benefit from attendant advantages.

When adjacent electric interfaces module IM be arranged to can by corresponding integrated NFCIO interface be positioned at other adjacent electric interfaces module IM exchange data and/or energy, this is especially favourable.Fig. 4 shows an one exemplary arrangement, it illustrates desired but nonessential at least about the situation of the equivalent arrangements of the NFC interface of corresponding (plane) antenna 7.In order to example, Fig. 4 shows string electrical interface module IM together, and wherein each module has housing 1a, 1b, the 1c ... of himself.Arrange at least one support 2 in the housing, and then by disposed thereon for (plane) antenna 7.For the purpose of simplifying the description, respectively illustrate exemplary magnetic field wire, the magnetic field line that such as can be formed between independent electrical interface module IM during data and/or energy exchange.Such as, broken magnetic field line 10a represented by broken line can be formed by the first interface module IM being arranged in housing 1a.Such as, these magnetic field lines 10a can engage in the region of (plane) antenna 7 of the second interface module with first interface module direct neighbor, makes it possible to by magnetic field function of exchange and/or data between adjacent interface module.Also can adopt in the same way for the second interface module, the object wherein in order to distinguish, show magnetic field line 10b with dot-and-dash line here.These magnetic field lines easily can certainly be embodied as and make them can also exceed adjacent interface module transfer energy and data.In this way, such as, gap and/or defect module can be bridged, and/or, as mentioned below, even can be identified as defective and/or be reconfigured.

In one exemplary embodiment, adjacent interface module IM is implemented as and makes adjacent electrical interface module IM form logical data bus by integrated interface IO, and this integrated interface IO can carry out addressing and/or control by least one front module or a primary module with higher control and/or supervising device.Such as, one of interface module can be assigned the function of primary module, or the special front module of serving as primary module be directed between adjacent electrical interface module IM side or adjacent electrical interface module IM.

In one embodiment, such as specify that adjacent electrical interface module IM forms ad-hoc network, in this case, bear the function of tonic chord for one in adjacent electrical interface module IM, and other electric interfaces module IM be adjacent is born from function.Such as, primary module role can be born for one in the electric interfaces module IM of the centre represented by housing 1b in Fig. 4 or the electrical interface module IM of outside that represented by housing 1a and 1c, and remaining electric interfaces module serve as this electric interfaces module from module.

The selection of primary module such as can be determined based on predetermined sequence.Such as, this selection can based on one or more following standard:

Product data

Configuration data

First operation interface module

Priority

The time of running off.

It should be pointed out that write and/or reading device RW can certainly bear the function of tonic chord, especially when wireless I/O interface.

In addition, write and/or reading device RW also can be connected to last user or even be connected to front module.

In order to example, a kind of possibility selected with reference to wireline interface IO brief description primary module.

Hereinafter, will adopt based on the example of CAN as many master control systems for I/O interface.By for I/O interface based on CAN, each user can become master control thus, that is, this system is so-called many master control systems.User's (i.e. electric interfaces module IM) of many master control systems especially sends data by the specific ID that other users can analyze.

Utilize CAN, such as, can set up master control function rapidly, this is because only authorize bus access to a side with limit priority in the case of synchronous transmissions.Such as, this address that can be bus master by such as lowest address is determined.In the case, other users can withdraw from.

In order to realize this, can guarantee in more higher protocol layer (such as application level or the 7th layer), other users (i.e. other electrical interface module IM) such as can only self transmission when corresponding master control so asks them.When lacking corresponding master control, then can specify that another electrical interface module IM bears this master control function.

This will be favourable, such as, in a failure situation, if master control is determined at random; In the case, and if main control module can not stop its transmission due to the determination of higher priority telegram (such as CAN), other users (such as electric interfaces module IM) will have to wait for until they receive transmission request etc. from new master control, and it can be determined according to identical mode (such as based on limit priority) conversely in advance.

Then, can specify, such as, ensure at more higher protocol layer, because of master control fault before, the electrical interface module IM that Puiescent, inoperative has a driven function always will send transmission now again to be asked.

In addition, can also specify, adjacent electrical interface module IM exchanges data by higher procotol via I/O interface, namely, for the I/O interface in ISO/OSI layer model, make to only have one or more comparatively deep layer (such as Physical layer) available, but utilize different agreement that upper strata or multiple upper strata can be used.Some examples of higher procotol be hospital bus bar, bus, RS232, ASI etc., wherein, such as, make the Physical layer of these procotols to use by the Physical layer of NFCIO interface.

In an embodiment of the present invention, can also specify that electric interfaces module IM stores from least part of configuration data of the electrical interface module IM of at least one direct neighbor, and monitor the availability of electrical interface module of this direct neighbor.In the diagram, such as, the electric interfaces module represented by housing 1b can monitor the electric interfaces module IM of the direct neighbor represented by housing 1c, or stores at least its partial configuration data.Whether monitoring can be carried out by different way, such as, to be existed or via target query by monitoring communications.Although only discuss monitoring in the above-described embodiment in one direction and store, the monitoring performing other adjacent electric interfaces module I O/1a can certainly be specified.In addition, this monitoring can also be installed into the electric interfaces module not only covering direct neighbor, but also covers farther electric interfaces module.Such as, can specify that the first interface module IM/1a in Fig. 4 also monitors electrical interface module IM/1c.

If find adjacent electrical interface module IM defectiveness now, then mistake can be forwarded to other interface module.Especially, mistake can be forwarded to main control module and/or front module and demonstrate.Alternatively or additionally, regulation mistake can also be forwarded to other device, such as supervising device.

If change affected electrical interface module now, then can specify, by the communication via interface, for stored electricity interface module IM/1b, check now the adaptability of alternative electrical interface module IM/1c with regard to stored configuration data of this insertion alternatively.

If provide this detection and be successful, then specify now, stored configuration data is sent to the electrical interface module be replaced.Certainly, this step can not also rely on inspection.

In addition, can also specify that storing adjacent electric connection module accordingly compares received configuration and the configuration still stored, and in successful equivalent arrangements situation, such as by sending proper signal by interface IO, only when having configured and the configuration that this is done has been sent to them, the operability of exchanged interface module is only allowed to discharge.This method is favourable for safety (son) system such as had as the predetermined safe integrated horizontal according to SIL such as IEC61508.In addition, owing to not needing other external control at present, be therefore convenient to very much the replacing of defect module, thus eliminate the expense of other necessary configuration this.

In another embodiment, can identify the abort situation in fault electrical interface module IM in multiple adjacent electrical interface module IM.

Determine that the one of the position of fault may be allow adjacent electrical interface module IM form logic chain.Such as, so the first electric interfaces module or front module or primary module can by continuing to be forwarded to next logic electric interfaces module IM from the signal of electric interfaces module IM in logic chain until reach chain any one end or until forward and do not cause any response, determine chain length.Such as, can be included in can the counter signals of increasing or decreasing when successfully forwarding for the signal of forwarding.The last parts of the logic that still can reach return to its position in logic chain, make corresponding first electric interfaces module or primary module or head module can make comparison according to known logic chain length before this now, to determine the length-specific of its whether matching logic chain, and whether errors present can not be defined as being close to the position in chain after last responder link according to the rearmost position of report.

At other in alternative or other embodiment, can also specify, the electric interfaces module IM of direct neighbor monitors the state of aforementioned electric interfaces module IM, and when breaking down, to the first electric interfaces module or primary module or head module reporting errors.

When primary module fault, can specify adjacent or even other electric interfaces module bear this function.

When there is mistake in system, such as, except trouble unit, website can also be divided into two or n independent particle system, and continue Local treatment.

Up to now, above with reference to NFC interface, but the invention is not restricted to NFC, on the contrary, it is only an example of near field transmission technology.Another exemplary near field transmission technology is the RFID substituted that such as can be used as NFC.

The present invention is also not limited near field tranmission techniques.The present invention can also realize the wired bus systems that electric interfaces module is networked by it, and wherein, use CAN etc. are as bus protocol.
